Comfortably hold the three points of "neck, arms, and waist" and get a beautiful posture. 【Point1】The "angle" of the backrest that maintains a natural S-shaped curve without a feeling of pressure The backrest angle makes it easy to sit without feeling pressured, and the backrest angle makes it easy to maintain a natural S-curve while being at ease, and the height of the armrests keeps you from slouching. 【Point2】"Armrest" that naturally creates a posture that does not lie down Why do we turn our heads? That's because there is no arm support. The armrests with a height derived based on anthropometric measurements support the arm holding the smartphone or book in a high position, so the eyes are facing forward and the neck and waist are not bent. 【Point3】Comfortably hold the boundary between the neck and shoulders "True high back" The longest class high back and moderate cushioning provide solid support to the back of the neck. In addition, in order to reduce the stuffiness of the back, the backrest has been narrowed to the limit. ●Product Outline Product name: Chair ais 44cm MUSTARD Seat height: 44cm Fabric color: MUSTARD (yellow) Leg Color: Medium Oak/Natural Oak Body size: Width 570, Height 1170, Depth 590-630 (mm) Weight :13.1kg Load capacity: 80kg Accessories: Instructions, 4 wooden ×legs, 4 wooden legs felt× 4, hex wrench for mounting [Fabric] 85% polyester, 15% rayon [Structural Members] Frame: Metal (steel) Leg: Natural wood (surface treatment; lacquered) Cushioning material: Urethane foam
